This issue has taken me a while to get to the bottom of due to diagnosing by trial and error. I’m concluding that there is an incompatibility between BT Whole Home’s AP Steering feature and the Apple MacBook Pro 16”.
The Symptoms: I can be working away quite happily on my MBP when all of a sudden I am unable to access anything over the network. The WiFi connection itself hasn’t dropped – the MBP still thinks it is connected to the same SSID, but I’m unable to pass any traffic over the connection. If I run ping tests to both internet and local addresses, 95% of packets are lost, with only the occasional reply suggesting something is still working. No other devices on my network have the issue including an older MacBook Pro 13” and a MacBook Air, plus dozens of various other gadgets I have scattered around – it is literally just this MBP 16”. Drop-outs would be at least daily.
Things I’ve tried:
I’m suspecting it’s something along the lines of BT Whole Home steering the MBP to another AP, but the MBP still thinking it’s connected to the original one which is now refusing traffic. But, the odd thing is that the Whole Home logs show that the MBP mac address did not hop between the APs, so that’s a spanner in that theory.
Anyway, for anyone else experiencing this issue - dive into the hidden steering menu and disable the AP steering option at the top.
For BT support – it’s easy to reproduce, please fix this because I don’t think that disabling steering is the best solution. Let me know if you need any other logs or anything. If I re-enable AP steering I’m bound to see the issue re-occur within 24 hours.
I'm experiencing similar issues with a 2020 Macbook Pro. Did you ever find a solution?
I did indeed... I purchased Asus ZenWifi access points instead. Absolutely rock solid for everything ever since.
